METHOD OF FORMATION OF INVAGINATED AREFLUX GASTRODUODENOANASTOMOSIS Russian patent published in 2009 - IPC A61B17/00 

FIELD: medicine; surgery.

SUBSTANCE: tube gastrectomy is followed with formation of a constrictor muscle representing a duplex seromuscular layer of width 14-15 mm on gastric stump. Gastroduodenoanastomosis is formed. After formation of the constrictor muscle, its lower edge with submucous layer is sutured to sew with a seromuscular-submucous layer of duodenal stump. The formed part of a muco-submucous layer of gastric stump is freely immersed in duodenal lumen as a drop valve. Invaginated seromuscular flat-topped are applied between duodenal wall at the distance 15 mm in distal direction from anastomosis and gastric wall at the distance 5 mm in proximal direction from upper edge of the constrictor muscle, on posterior and anterior gastric and duodenal walls. Knots are made. Anastomosis and the constrictor muscle are invaginated in duodenal lumen.

EFFECT: prevented inconsistency of anastomosis, development of anastomositis, stricture formation, cicatrical and adhesive processes.
